The HMS Axis Inverters from Bosch Rexroth Indramat comprise DC-bus powered inverter power sections (HMS01/HMS02) used within IndraDrive systems to create single-axis servo drive controllers.
These units are designed to be supplied from a compatible IndraDrive DC power supply (such as an HMV) through the L+ and L− DC-bus connection, with external branch-circuit protection applied per the supply system limits. Depending on the specific inverter size, the series provides a three-phase motor output with voltage capability up to 3 × AC 0…500 V and continuous output current ratings that span roughly 15 A to 250 A. For control and machine integration, HMS inverters use a 24 V control-voltage input and provide an interface for motor temperature monitoring plus control of an external 24 V motor holding brake supply (with HMS02 including an electromechanical brake contact designed for high switching life). Installation is structured around control-cabinet mounting and cooling requirements, mandatory protective-earth connection, and defined shielding/strain-relief and DC-bus accessory options to support robust wiring and EMC performance.
